Collagen diseases affecting the foot

Area of Science:

• Rheumatology
• Orthopedics
• Podiatry

Background:

• Arthritis significantly impacts foot and ankle function.
• Understanding different arthritis types is crucial for diagnosis and treatment.
• Foot involvement in systemic inflammatory conditions is common.

Purpose of the Study:

• To classify and describe various forms of arthritis affecting the foot.
• To highlight common causes and presentations of foot arthritis.
• To provide an overview of osteoarthritis, seronegative spondyloarthropathies, and psoriatic arthritis in the foot.

Main Methods:

• Literature review and classification of arthritis types.
• Discussion of etiological factors and joint involvement.
• Categorization based on clinical presentation and underlying conditions.

Main Results:

• Osteoarthritis commonly affects the first metatarsophalangeal joint and ankle, often secondary to trauma.
• Charcot destruction, secondary to diabetic neuropathy, is a frequent cause of secondary osteoarthritis.
• Seronegative spondyloarthropathies like ankylosing spondylitis and Reiter's syndrome can affect the foot.
• Psoriatic arthritis presents in three distinct variants affecting the foot.

Conclusions:

• Accurate classification of foot arthritis is essential for targeted management.
• Diabetic neuropathy and prior trauma are key contributors to secondary foot osteoarthritis.
• A comprehensive understanding of various arthritis types aids in diagnosing and treating foot conditions.
